Definitions

  • the subject matter disclosed herein relates to power systems. Specifically, the subject matter disclosed herein relates to an exhaust hood for a turbine system and methods of installing the exhaust hood.
  • Low-pressure (LP) steam turbines utilize exhaust hoods to move exhaust steam from the last stage buckets of the turbine to condensers.
  • the steam discharges from the last set of the last stage buckets to an exhaust flow passage formed within the exhaust hood.
  • the exhaust flow passage is formed by the outer surface of an exhaust cone, which surrounds the rotor of the turbine, an end wall of the exhaust hood, and a flow guide attached to an inner casing of the LP steam turbine system.
  • the exhaust hood, cone and flow guide are custom made to create a unique exhaust flow passage for each LP steam turbine. The custom components are made to optimize performance in the LP steam turbine.
  • the custom shape and configuration of the exhaust cone and flow guide are, in-part, dependent on the size and location of the last stage buckets, the type of condenser used (e.g., water cooled, air cooled, etc.) and the desired aerodynamic performance to maintain within the exhaust hood.
  • the exhaust cone is fixed to the exhaust hood, and the flow guide is fixed to the inner casing of the LP steam turbine.
  • the respective exhaust flow passage is not easily modified.
  • the re-design of the exhaust flow passage is time consuming and resource-intensive.
  • in-field modifications are expensive and involve major alterations (e.g., torch cutting, grinding, welding, etc.) to the exhaust hood and its components.
  • the exhaust hood must be modified to create a new exhaust flow passage.
  • the exhaust hood must be replaced as a whole when modifications will be too costly or diminish the efficiency of the LP steam turbine system. While operation costs may be reduced by utilizing interchangeable components of the LP steam turbine systems to meet changing power demands, optimum operation often requires new or extensively modified exhaust hoods to maintain efficiency within the LP steam turbine system.
  • each exhaust hood is designed for a specific LP turbine system having last stage buckets with distinct dimensions.
  • a new exhaust hood must be manufactured with exact dimensions to fit the specific LP turbine system. That is, a single exhaust hood cannot be configured to fit a plurality of LP turbine systems, but rather, each exhaust hood is custom to the LP turbine system that utilizes the hood. Similar to the exhaust cone and flow guide, this customization requirement of the exhaust hood increases cost of operation and maintenance for conventional LP turbine systems.
  • the turbine exhaust hood includes: a housing having an end wall, the end wall including a first portion of a releasable coupling; and a first radially inner steam guide structure disposed within the housing, the first radially inner steam guide structure including a second portion of the releasable coupling, integral with a first end of the first radially inner steam guide structure, wherein the first portion and the second portion of the releasable coupling releasably couple the first radially inner steam guide structure to the end wall.
  • a first aspect of the invention includes a turbine exhaust hood having: a housing having an end wall, the end wall including a first portion of a releasable coupling; and a first radially inner steam guide structure disposed within the housing, the first radially inner steam guide structure including a second portion of the releasable coupling, integral with a first end of the first radially inner steam guide structure, wherein the first portion and the second portion of the releasable coupling releasably couple the first radially inner steam guide structure to the end wall.
  • a second aspect of the invention includes a steam guide structure having: a body having: a first end including a first portion of a releasable coupling, the first end configured to be releasably coupled to a turbine exhaust hood via the first portion of the releasable coupling; and, a second end located substantially proximate the first end and positioned within the turbine exhaust hood.
  • a third aspect of the invention includes a method.
  • the method includes: providing a first steam guide structure; releasably coupling the first steam guide structure to a turbine exhaust hood; and installing the turbine exhaust hood onto a first turbine system, the first turbine system including a first set of last stage buckets having a first length.
  • aspects of the invention relate to a turbine exhaust hood. Specifically, as described herein, aspects of the invention relate to a low-pressure turbine exhaust hood having interchangeable radially inner and outer steam guide structures that correspond to specific last stage buckets used in a steam turbine.
